It's the Paper, Stupid --Dickeson

Keeping Time

Follow the paper into WIP—work in process. Note the date and time the paper enters production. Next, note the date and time it leaves production and becomes part of a receivable. Subtract exit time from entry time and we know the WIP dwell-time. The greater the WIP dwell-time, the less the profit. (We're not making a nickel while the paper is in WIP.)
